A graphene-based affinity nanosensor for detection of low-charge and low-molecular-weight molecules†
Abstract
This paper presents a graphene nanosensor for affinity-based detection of low-charge, low-molecular-weight molecules, using glucose as a representative. The sensor is capable of measuring glucose concentration in a practically relevant range of 2 μM to 25 mM, and can potentially be used in noninvasive glucose monitoring.
